About the Kawasaki KDX400

Fork, steering-head and front-brake service for the KDX400’s listed 1979–1980 applications.

Kawasaki Motorcycle Logo

A KDX400 front-end service starts by separating fork leakage from rough steering or brake-control wear. Inspect each assembly before dismantling it and record any replacement forks, steering stem or controls. That record is especially useful when comparing KDX400 and KDX420 parts: some service items overlap, but the steering-bearing kits featured in these guides differ.

Separate steering wear from fork problems

Inspect steering movement and bearing condition alongside the forks, but identify which assembly causes any stiffness or play before ordering. A replacement fork or steering stem changes the fitment checks needed. For the front drum brake, inspect the shoe surfaces, drum, cam and cable mechanism together; lever shape alone is not enough to confirm compatibility.

Know your KDX400 before choosing partsKDX400 repair checkpoints

Use the checkpoints below to prepare the parts list for your repair.

1979–1980 service

A shared range, separate checks

The four featured items list KDX400 1979–1980. Confirm the dimensions and fitted assembly for each item rather than treating the matching dates as a complete-service kit.

KDX400 versus KDX420

Steering kits differ

The KDX400 guide features the SSK-904 steering kit; the KDX420 guide features another kit. Match the stem and bearing seats before selecting either.

Brake control

Inspect from lever to drum

Check lever fit, cable operation, brake-cam movement and shoe condition. Replacing one worn component does not establish that the rest of the front brake is serviceable.

Identify your motorcycle before orderingKDX400 identification checklist

Record the motorcycle’s identification and check for replacement assemblies before choosing service parts.

  • Record the KDX400 frame identification and model year, and note any replacement forks or steering stem.
  • Compare steering-bearing dimensions and fork-seal measurements with the removed components before purchase.
  • Identify the front brake shoes, lever pivot and cable attachment from the installed drum and handlebar controls.

Kawasaki KDX400 parts for repairs & restoration

Choose a repair below. Each example keeps its stated model and years even when you change filters. Check the product’s full fitment, contents and quantity before ordering.

Restoring or customizing your KDX400?

For KDX400 handlebars and grips, check the existing throttle and cable-operated controls before choosing a new bar shape. Clamp diameter, grip bore and enough cable travel are required for clear steering and normal control operation.

Universal accessories require a mounting and clearance check and are not a confirmed KDX400 fit.

Kawasaki KDX400 parts questions

What years do the selected KDX400 chassis parts list?
The featured fork seals, steering-bearing kit, front shoes and brake lever list KDX400 1979–1980. Confirm each component’s dimensions and application before ordering.
Are KDX400 and KDX420 steering-bearing kits interchangeable?
The selected kits are different. Use the application for the correct model and compare the installed steering stem and bearing dimensions, particularly if the front end has been replaced.
Will new fork seals fix steering-head play?
Fork oil seals and steering bearings perform different jobs. Inspect the steering bearings and stem adjustment separately from fork leakage or sliding play before choosing parts.
What should I check when ordering a KDX400 front brake lever?
Compare the lever pivot, perch, cable attachment and stop. A previous owner may have fitted different controls, which can require a lever other than the original-style application.
